Dell NetWorker 19.9 Administration Guide

Scanning for libraries and devices

Devices already known to the NetWorker server can be seen in the enterprise hierarchy in the navigation tree. Use the Scan for Devices option described here to find devices that are not yet known to the NetWorker server. Be aware that:

  • A storage node must be added to the hierarchy before its devices can be scanned.
  • The Scan for Devices option does not detect file type or advanced file type devices.
  • By default, the Linux kernel configures a maximum of 128 st devices by default. Refer to The inquire command and the Scan for Devices operation do not detect more than 128 tape devices if the Scan for Devices option does not detect more than 128 tape devices on Linux operating systems.
  • The Scan for Devices option scans for only 256 drives. For additional drives, you should either configure them manually or configure a secondary storage node for the other drives to be detected.
  • A specific network interface can be used between the NetWorker server and the storage node when scanning for devices. Identifying a specific network interface for device scan operations provides more information.
  1. In the Console window, click Enterprise.
  2. In the navigation tree, select a NetWorker server.
  3. In the Name column of the Host detail table, double-click NetWorker. The NetWorker Administration window for the selected server opens. Note that while multiple NetWorker Administration windows can be open simultaneously, each one displays information about only one host or server.
  4. In the Administration window, click Devices.
  5. In the navigation tree:
    1. Right-click the server name, and select Scan for Devices.
    2. Click the storage node to be scanned.
    3. If the appropriate storage node is not listed, click Create a New Storage Node.
    4. When creating a new storage node, replace the default value in the Name field with the fully-qualified domain name or short name of the new storage node.
    5. Fill in any required information, such as whether to scan for SCSI or NDMP devices and whether to search all LUNs.
    6. Click Start Scan. To monitor the scan activity, click Monitoring, then select the Log tab. Any relevant status information is displayed there.
  6. Return to the Devices navigation tree to view the refreshed device information (configured and unconfigured):
    • To display SCSI and NDMP libraries available to the NetWorker server, select Libraries in the navigation tree. Any available library or silo appears in the Libraries detail table.

    • To display stand-alone devices available to the NetWorker server, select Devices in the navigation tree. Any available stand-alone device appears in the Devices detail table, along with devices available in libraries.

    • To display the libraries and devices that are available to a storage node, select the storage node in the navigation tree. Available storage nodes appear in the table. Double-click a storage node to see its details, along with the devices that are available in the storage node.
